I'd like to emphasise Alan's point, by adding/pointing out that it is
perfectly possible to write e.g. Object Oriented code in e.g. a procedural
language like C, which obviously doesn't support the notion of objects
explicitly in the language, although then it's up to you to come up with
conventions and infrastructure to support the concept of object orientation
in your program.

As examples, the X Window System was originally written in C but using
object oriented principles, also GTK+ is an object oriented cross platform
widget set written in C.  It relies on a library called GObject for
realisation  of object orientation. See e.g.
http://en.wikipedia.org/wiki/GObject
